Iran acted right after the election, almost like they knew ahead of time they would have to filter the WWW. They cut out going traffic to zero, and slowly applied filters and brought it back up. The speed and depth of the operation indicates it was expected they would need to shut off parts of the WEB. It also indicates a dos attack of between 11 and 14 Gbps, would backup and take it all off line, Government too. A very doable dos attack. But thats up to the protester, the Iranian people. Currently there is plenty of bandwidth. Details: Internet Anthropologist Think Tank: Iran's Blocking their Backbone, WWW Gerald Tactical Internet Systems analyst. .
